I was searching for something bigger and found these:

81 qt each... and 4 for, like, $130 shipped total... not to mention airtight?
Sweet.
I'm gonna fill two of them (by emptying out the 2 other, non-matching coolers I have full already), throw some beads in there, and lose them in a nice and cool area.
Running out of space sucks... this should keep that problem at bay for a time.
